LANSING – Michigan Attorney General Bill Schuette said Wednesday he will wait until sentencing hearings for Larry Nassar are completed in both Ingham and Eaton counties before announcing his plans for a review of Michigan State University's role in the sex abuse scandal.

Schuette, speaking on "Michigan's Big Show," a syndicated radio program hosted by Michael Patrick Shiels, said now is the time for Nassar's victims to speak and "I'm not going to upstage them."

Nassar, an MSU doctor who has pleaded guilty to federal child pornography charges and state-level sexual assault charges, is accused of abusing more than 150 girls and young women, most of them MSU gymnasts, under the guise of providing medical treatment.

His sentencing hearing in Ingham County Circuit Court with victims giving their statements concluded Wednesday, its seventh day before Judge Rosemarie Aquilina. Aquilina sentenced him to 40 to 175 years in prison as part of a plea deal on seven counts of first-degree criminal sexual conduct involving more than 160 girls and women over more than two decades.

Schuette, who is seeking the Republican nomination for governor, said Nassar's next sentencing hearing, in Eaton County Circuit Court, is expected to get under way Jan. 31.

"Once that's done, there will be an immediate announcement," Schuette said.

He said he will call for "a full review, a transparent report, and recommendations so this never happens again."

Last week, the MSU Board of Trustees, which, along with President Lou Anna Simon, is under fire for not adequately investigating complaints about Nassar and not acting more quickly to stop the abuse, asked Schuette to conduct a review.

Andrea Bitely, a Schuette spokeswoman, would not say whether the inquiry is already under way and only the announcement is pending, or whether Schuette wants the sentences handed down before he begins the review.

Mark Totten, a law professor at MSU and the Democratic candidate for attorney general in 2014, said Wednesday that no delay is warranted and a "review" is not what is needed.

"To be very clear, prosecutors don’t perform 'reviews; and offer-up 'recommendations,' " Totten said in a Facebook post. "They conduct investigations and bring criminal charges, if the evidence demands."

Schuette, who has faced criticism for not investigating MSU's role in the abuse scandal sooner, said on the radio program that he and his team "nailed Nassar" on sexual assault charges and he made sure, as part of his plea agreement, that every Nassar victim who wanted to speak at his sentencing hearing had an opportunity to do so.

House Speaker Tom Leonard, R-DeWitt, appearing with Schuette on the same radio program, said an investigation is absolutely needed. "We need to know who knew what, when they knew it," said Leonard, a Republican candidate for attorney general.

Leonard, who called for Simon's resignation in December, blasted MSU trustees Wednesday and said "if they won't step up and do their jobs, they need to step down as well."

He criticized the "arrogance," and "tone deafness" of MSU trustees — an apparent reference to comments Tuesday by Trustee Joel Ferguson, who scoffed at the idea of an NCAA investigation over what he described as "this Nassar thing." He later apologized.

Leonard said he was glad to hear the NCAA is now prepared to investigate MSU over the Nassar scandal.

"Maybe, just maybe, these guys might start waking up if they find out they might lose scholarships," he said.

Trustees "have put sitting in a skybox, four days a year at a football game, above these ladies."
